[U-Boot] [PATCH] bootm: fix size arg of flush_cache() in bootm_load_os().

Variable _load_end_ points to end address of uncompressed buffer (*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed size with sizeof(ulong) is grossly incorrect in flush_cache(). It might lead to access of address beyond valid memory range and hang the CPU. Tested on MIPS
